Christian, what you call the "volume" of a microphone is technically known as its "sensitivity." That is the voltage which the microphone produces for a given sound pressure level.

In those terms, the M 149 Tube has the highest sensitivity of any microphone that I have ever heard of. So maybe it isn't the best choice for comparisons that you make with only your ears, because the M 149 will always "win" by a considerable amount. The real question is, how large is that amount--the difference in sensitivity between your two microphones?

If we take the cardioid setting of both microphones for comparison, the M 149 has a rated sensitivity of 47 mV/Pa while the M 269 c has a rated sensitivity of 10 mV/Pa with its pattern switch in the "F" setting, or 15 mV/Pa in its special, cardioid-only setting. That is a difference of either 13.4 dB (M 269 in "F" setting) or 9.9 dB (M 269 in cardioid setting). Either way, that's a large difference. And if by chance your M 269 is set for 50 or 150 Ohm output, that difference will increase by a further 6 to ca. 10 dB, depending on your preamp.

Do you perhaps have another, more typical (in its sensitivity) professional condenser microphone that you can compare with your M 269? Or can you measure the difference in sensitivity between your two microphones, to see whether it is similar to the expected difference?

--best regards
